Efficient dredging residual water treatment system

The invention discloses an efficient dredging residual water treatment system which comprises a water ejector, a working pool and a plasma deflocculation device. One end of the water ejector is connected with a residual water pipeline and is used for transporting dredging residual water to a working pool; the working pool internally comprises a reaction chamber, a mixer is arranged in the reaction chamber, the mixer is communicated with a circulating pump through a pipeline, the circulating pump is used for circulating fluid in the mixer and controlling the flow speed of the fluid, and an air compressor is arranged in the reaction chamber; the air compressor is used for providing air stirring and adjusting the stirring strength; the working pool is used for separating the magnetic powder flocculation sludge from the treated dredging residual water; the plasma deflocculation device is used for performing deflocculation treatment on the magnetic powder flocculated sludge. By means of the device, it is guarantee
